                          hide show

                          What are the wiring terminals on the IEC LRD* overload relays?

                          Product Line:
                          Tesys D line Overload Relays
                           
                          Resolution:
                          The normally closed overload contact are terminals 95 & 96; and the normally open overload contact are terminals 97 & 98.
                          T1 T2 and T3 are the load terminals. 

                          The normally closed control circuit contact will open when there is a fault, this contact is typically used in series with the control circuit. 

                          The normally open trip signal contact closes when a fault occurs which is typically used to control a pilot light, or alarm. 

                           

                          What overload to suit LC1D95U7 need to be 80-104A

                           Part code for the overload LRD3365

                          What is the reference for the separate mounting kit for LRD4369 overload relay

                          The LRD43xx type of thermal overload relays are directly mounted to the contactors LC1D115 & LC1D150 only. There is no separate mounting kit for the LRD43xx.

                          If a separate mounting is required for the contactors LC1D115 or LC1D150 type, then LRD336xx shall be selected as these range of overload relays have indepentdent mounting and have similar setting range and are of Class 10A.

                          How to use LRD01…35 LRD33•• & LRD43•• and LRD33** as an indepentent relay?

                          The LRD relays has a solid tag to be used with LC1D** contactors. If you are not using LC1D contactors then using the following accessories you can terminate cable directly.

                          For LRD01…35 use the following part: LAD7B106
                          For LRD33•• & LRD43•• (3) use the following part: LA7D3064

                          How Can the LC1D50AU7 Contactor be mounted?

                          Two ways -  the LC1D50AU7 can be DIN Rail mounted and Plate mounted.

                          See the attached datasheet for further information.

                          What overload can be used with an LC1D65AU7?

                          You can use the Everlink range which is LRD313 - LRD365

                          What is the replacement for the old thermal overload relay LR2D3359?

                          The part number is as follows: LRD365

                          Is the LR9D5369 overload still available

                           Yes it is

                          What is the overload for the LR2D Everlink range 23-32 Amps?

                          The correct code is LRD332.

                          What is difference between LC1D50U7 and LC1D50AU7?

                          Following are the differences between the LC1D50U7 and the LC1D50AU7:

                          LC1D50AU7 has everlink terminals.
                          LC1D50AU7....is slightly larger case and accommodate LRD3XX overloads
                          Whereas
                          LC1D50U7 contactors accommodate LRD33XX overloads.

                           

                          What is the replacement for LR2D3357?

                          What is the part number of a 23A -32A overload to fit LC1D40U7 contactor?

                          LRD3353 is a 23A -32A overload to fit LC1D40U7 contactor.
